South Africa recently witnessed a catastrophic natural disaster that resulted in the loss of life, livelihoods, and infrastructural damage. This occurred in KwaZulu-Natal where hundreds of people lost their lives as a result of extensive flooding and mudslides. President Cyril Ramaphosa declared a national state of disaster to which we should all respond. Specific reference was made to the public and private sectors, as well as civil society.

While I applaud the various stakeholders that have extended a helping hand, my heart bleeds for the vulnerable groups whose voices remain unheard, even under normal circumstances. One cannot help but wonder if aid will reach the isolated regions that suffered the adverse effects of these heavy rains, or if all developmental efforts will be prioritised to certain economic hubs of the province such as the eThekwini Metro and the capital, uMgungundlovu.

KwaZulu-Natal is among the poorest provinces in the country. Corroborating this claim is a report that was released by Statistics South Africa earlier this year which reveals that about 52% of the province’s population are considered to be ‘poor’,and live at the lower end of the poverty line.

Drawing from my experiences of the rural communities of KwaZulu-Natal with whom I have worked, many suffer from the triple challenge of poverty, inequality, and unemployment, and rely on agriculture for their livelihood and to put food on the table. Their supplementary income is obtained from government support grants. The graphic scenes that have been shown on the media illustrate the devastating effects of the heavy rains in regions within the agricultural sector. Fields have been washed away, crops and livestock have been lost. This is happening when the province is still trying to resuscitate its economy after the widespread looting that took place in July last year, which had a calamitous effect on businesses and livelihoods.

While this is an injury mainly for the people of KwaZulu-Natal, it is my wish that we all join hands in contributing towards the restoration of livelihoods. In agreement with the president’s assertion, we can all play a part in rebuilding the province. This includes institutions of higher learning, particularly the Community Engagement Directorates whose mandate is to drive socioeconomic development to external communities.

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
